JOHN T. BOLTON, OF NEW HAVEN, CONNECTICUT.

FABRIC-GUIIDING MECHANISM.

Application filed March 24, 1922. Serial 1T0. 546,248.

To all whom it may concern: Be'it known that I, JOHN T. BOLTON, acitizen of the U nitcd States, residing at New Haven, in the county ofNew Haven and State of Connecticut, have invented certain new and usefulImprovements in Fabric- Guiding Mechanisms, of which the following is aspecification, reference being bad therein to the accompanying drawings.

This invention relates to new and. improved fabric guiding mechanism,referring more particularly to mechanism for controlling the movement of.a piece of fabric so that it may be uniformly rolled, each convolutionof the rolled fabric being exactly over the precedingconvolution, thusleaving one end of the roll flat.

It is the object of this invention, among other things, to providea'device of the character mentioned with a view to compactness, in whichthe number of parts are few, the construction simple, cost of productionsmall, and efiiciency and operation high.

The improvements in the details and arrangements of parts will beapparent from an inspection of the accompanying drawings in connectionwith the description hereinafter contained, and wherein a preferredembodiment of the invention is disclosed for the purpose of imparting anunderstanding of the same.

In the drawings, wherein like characters of reference designate likeparts in the several figures;

Figure 1 is a front elevation, partly in section, of my improvedmechanism;

Figure 2 is a transverse sectional view thereof, taken generally uponline 2-2 of Figure 1;

Figure 3 is an enlarged fragmentary detail of a portion thereof, takengenerally upon line 33 of Figure 1; and

Figure 4 is an enlarged plan of the movable cam and someof its adjacentmechamsm.

It is desirable in winding fabric Whether taken from roll, a box, orother device where it has been folded or plaited, that the ends of thecompleted roll should be flat and smooth and that in the windingoperation the lateral position of the fabric be maintained in auniformpath so that such a result may be obtained. Efforts have been heretoforemade to bring about such desirable roll winding, but so far as atpresent advised, these attempts have always been confined to mechanismsthat contact with the fabric near the edges only and sometimes with anindependent and supplemental de vice located lherebetween, and thesehave usually been arranged at an angle to the width of the fabric. Inpractice, this type of mechanism has been found quite ob1ectionable,especially with some classes off-abric, because in their operationthepressure is only applied where the mechanism contacts with the fabric,this distorts the sha c of the fabric, produces a gathering, a onelilingfold or a wrinkle in the fabric adjacent to the edges thereof, whichfrequently remains and cannot be readily smoothed 'or ironed. out.Obviously, .with fabric of very fine l'GXtUIQ/OT having a print orfigure thereonor therein, such distortion is especially objectionable.Then again, with such mechanism, each of the devices is separate andindependent of every other one and must be arranged in a predeterminedosition relatively to each other, frequent a dlfficult task.

All of these, and other objections, that are known to those versedjn theart, are overcome in my improved mechanism, wherein the device is selfcontained,,in that it'is a single unitary structure provided with aplurality of members that successivel 0on tact with and are in partcontrolled y the fabric throughout substantially the entire widththereof, and apply. a lateral pressure that is exerted throughout theentire width by the sleeve 13 and are held against endwise movement bythe collars -14. v

Located equally distant about the axle of the shaft 11 are a pluralityof rods 15, each being provided with a shoe 16 at each end with a camlug 17 thereon. All of the shom at one end of the rods 15 are connectedwith oneof the reel heads 12 by links {18 that are hinged atone end tothe shoes y the pins 19 and at the other end to the reel head by thepins 20. The links are held against lateral movement by the lugs 21thereon that pass through radial slots 22 in the flange of the reel head12. These several rods 15, constructed and associated with the reelheads 12, as above described, move in a rotary path about the shaft 11and are capable of a synchronous movement parallel with the axis of saidshaft.

Each of the rods 15, may, if desired, provided upon their outer faceswith a friction member 23, which may be either of wire cloth, rubber orother similar device that will grip the fabric and hold it in contacttherewith. As shown in Figure 1, this friction member 23 extends theentire length of each of the rods 15, but it may be shorter if sodesired.

Adjacent to the inside of each of th standards 10 and fixed in relationthereto are the frames24, upon each of which is a projecting lug 25within which is fixed the rods 26 and 27. Upon the inner face of one ofthe frames is a cam 57 and pivotally connected to the other frame 24 bythe pintle 58 is the movable cam 28 having a cam face 29 thereon, and aslotted arm'30.

The reel, composed of the reel heads 12, rods 15, and connectingmechanism, is rotated in the direction of the arrow in F i ure 2 by thefabric designated 59 traveling in the same direction. A lateral movementof the bars 15, that is, parallel with the axis of the shaft 11, isaccomplished by engagement thereof with the cam 57 at one end and by themovable cam at the other end, and when out of contact therewith the barstravel only in a rotary ath being held against endwise movement by thesubstantially parallel inner faces of the frames 24, substantially asshown in Figure 1. The space between the ends of the lugs 17 on theopposite ends of the rods 15 is slightly less than that between theparallel inner faces of the frames 24 so that no friction is created bytheir otherwise constant contact therewith. The position of the cam 28is such that the lug 17 contacts with the cam face 29 when the same istraveling through a rotary path at the top of the reel, at which timethis particular rod 15 is out of contact with the fabric. The lug 17 atthe opposite end of the rod is opposite the low face 31 adjacent to thecam 57 upon the frame 24. This rod, moved as above described, to theleft in Figure 1, is, it will be remembered. constantly rotating and isthus brought into contact with the fabric 59 (see Figure-2) in itslaterally extended position. As soon. however, as the rod contacts withthe fabric, the shoe 16 thereon op osite the cam 28 engagesthe cam 57 anthe rod is moved axially during its rotary travel to a position whereinthe said lugs will pass between the parallel faces of the frames 24,during which time the fabric is moved laterally therewith. Thereafterthe fabric travels in this new path and is taken off the reel onto arollor such other device as may seem necessary or desirable. When therods 15 of the reel move in the same rotary path no lateral movement isimparted to the fabric, but contra when the rods are actuated axially.This lateral movement of the fabric is controlled in my deviceautomatically by the fabric itself, by mechanism about to be described.

Adjustably secured in one of the standards 10, is an air plug 32 havingan air chamber 33 therein and atfixed thereto is the ca 34, betweenwhich and the plug is a flexible diaphragm 35, connected with the cam 28by the link 36.

Leading into the air plug 32 is an inlet pipe 37, which connects with aport 38 that extends from the chamber 33. This pipe 37 extends from aunion 39, joined by a pipe 40 to a vacuum cylinder, not shown. \Vhen thevacuum is maintained the diaphragm 35 is flexed downwardly and throughthe link 36 moves the cam 28 upon its pivot mounting, lifting the camface 29 upward and out of the path of the lugs 17 so that the samepasses thereby without contacting therewith. The means for automaticallycontrolling this vacuum comprises a bracket 41, which is movable uponthe rod 26 and held against rotary movement thereon by itsengagementwith the rod 27 (F igure 3). In this bracket is a rock shaft 42 having ablock 43 fixed thereon, within which is secured a rod 44 having anadjustable weight 45 thereon and a trip arm 46 terminating at its lowerend in a contact finger 47, that projects upon both sides thereof asubstantial distance so as to be entirely certain that it will beengaged by the moving fabric.

Also fixed on the rock shaft 42 is a closure plate 48 having a stop arm49 connected therewith.

Secured in the bracket 41 by any referred means, is a pipe 50 formed wita curved end 51, which terminates a slight distance in advance of theface of the closure plate 48 when the stop 49 is in contact with thebracket 41, as shown in Figure 1, thereby leaving a slight space 52therebetween. A flexible tube 53 connects the pi e 50 with the union 39preferably throu arigid pipe member 54. This flexible tu 53 is providedso as to accommodate the movement of the bracket 41 along the rods 26and 27 and be operative in any one of such adjusted positions. Thisbracket 41 may be secured in any of its adjusted positions by a screw 55or the like, or it may be held in its adjusted positions through aconnection with another co-operating mechanism and a stud 56.

The weight 45 is so adjusted upon the rod 44 as to actuate the rockshaft 42 and maintain the end of the stop fin er 49 against the bracket41, thus leaving t e open space 52 in front of the curved and of thepipe 50. When the parts are in these relative positions there is novacuum in the air chamber 33, the same being destroyed by reason of theleakage at the open space 52, at which time the weight of the movablecam 28 is such as to cause it to occupy its down position, substantiallyas shown by full lines in Figure 4. The cam 28, now being in the path ofmovement of the lugs 17, will impart lateral movement to the rods 15 asabove described. When lateral pressureis applied to the contact finger47 the closure plate 48 is actuated so as to'move the face thereof intocontact with the end of the pipe 50, thus closing the space 52 andsealing the vacuum system. The movable cam 28 is now actuated throughthe movement of the diaphragm 35 and lifted out of the path of saidlugs, thus permitting the several rods 15 to travel in a uniform rotarypath, at which time no lateral movement is imparted to the fabric on thereel.

As the position of the bracket 41 is adjusted so that the finger 47rides against the edge of the fabric, it is obvious that when the fabricis traveling in a correct path the vacuum system is closed, the movablecam 28 is out of the path of the several rods 15 and the fabriccontinues to travel in its defined correct path-.- If, however, thefabric does not contact with the finger, as above indicated,- there isno pressure thereon, the rock shaft 42 is actuated through the weight 45and the stop arm 49 is brought up against the end of the bracket 41,thus destroying the vacuum. The weight of the cam 28 now causes it tomove downwardly and in its then position moves the rods 15 successivelyparallel to the axis of the shaft 11, which rods then automatically asthey contact with the fabric-move the same'laterally until it is againbrought into contact with the finger 47, when pressure being thenapplied thereto, the vacuum system is sealed, t e cam 28 is lifted andthe fabric continues to travel in its predetermined path as before. Aseach successive rod, when it contacts with the fabric exerts a slightlateral pressure thereon, a very extended lateral movement may beapplied 'to the fabric, if necessary to bring it into contact withthefinger 47. As the rods 15 contact substantially through the entire widthof the fabric, it is obvious that no portion thereof is distorted, andas the mechanism is entirely automatic in its operation, the resultsobtained are obviously certain, fixed and definite, and the efliciencyof the device extremely high, while the mechanism itself is quite simplein its character and is easily constructed and readily assembled, andwhen so assembled not liable to be easily disarranged or get out oforder.

As shown and described herein the movable cam 28 is lifted out of thepath of the lugs 17 by the diaphragm through the 'action of the vacuumthereon. Obviously the connection between the diaphragm and movable cammay be so arranged however that the reverse movements will result, thatis, the vacuum through the diaphragm will hold the movable cam in itsdown position in the path of the lugs 17.

There are minor changes and alterations that may be made within myinvention, aside from those herein suggested, and I would therefore haveit understood that I do not limit myself to the exact constructionherein shown and described, but claim all that falls fairly within thespirit and scope of the appended claims.
